For PA/PAA ≥ 10 bar

Accuracy ± 0,05 %FS, with KELLER calibration certificate ex works (standard)

Keller uses pressure sources to calibrate its products that are at least four times more accurate than the product to be tested. This enables us to produce products in our factory with an absolute accuracy of up to ± 0,05 %FS.

Precision ± 0,01 %FS / ± 0,025 %FS, with KELLER calibration certificate ex works

Additional measurement work and selection of a specific pressure transducer means that optimum repeatability is guaranteed for selected pressure transmitters and digital manometers. Owing to the residual measurement uncertainty of the pressure sources used at its factory, KELLER cannot provide any verification of measurement accuracy at scales below ±0,05 %FS for these ultra-precise devices. KELLER therefore uses the term "precision" to denote the ability of a pressure transmitter or manometer to repeat measured values within a tolerance of 0,01 %FS based on the pressure sources used at the factory.

Accuracy ± 0,01 %FS with DakkS (German accreditation body) certificate, issued by an external accredited calibration laboratory

By calibrating the zero point and performing amplification via the digital interface, an accredited calibration laboratory (ilac.org) can adapt ultra-precise KELLER products to their more accurate pressure sources and record the results.External calibration to an accuracy of up to ± 0,01 %FS is performed in accordance with the guidelines set out by the German Calibration Service (DKD) and is conducted under reference conditions without any consider-ation of long-term effects.

Series 33X – Software, scope of delivery and accessoriesModbus interface

The X-line products have a digital interface (RS485 half-duplex), which supports the MODBUS RTU and KELLER bus protocols. Details of the communica-tion protocols can be found at www.keller-druck.com. Documentation, a Dynamic Link Library (DLL) and various programming examples are available for in-tegrating the communication protocol into your own software.

Interface converters

The connection to a computer is established via an RS485-USB interface converter To ensure smooth operation, we recommend the K-114 with the corre-sponding mating plug, robust driver module, fast RX/TX switching and connectable bias and terminating resistors.

"CCS30" software

The licence-free software CCS30 is used to carry out configurations and record measured values.

Measurement collection• Live visualisation• Adjustable measuring and storage interval• Export function• Parallel recording in bus operation• Up to 100 measured values per second

Configuration• Call up of information (pressure and temperature

range, software version, serial number etc.)• Readjustment of zero point and amplification• Rescaling of analog output (unit, pressure range)• Adjustment of low-pass filter• Selection of instrument address and baud rate
